Correction : alpha wolves
Did the magnetar wave that hit earth on Dec. 27, 2004 add to the growing climate change?
"The first 200 people" but will everybody after that? Seems like you're using FOMO to get people to subscribe. You've been using the same link for years so those first 200 people must have already occurred.
11:00 the warning clearly says theres danger from intramuscular injection and intravenous. Right after you day theres no worry because they only use intramuscular?
@thingthing899 I re-watched that portion of the video and re-read your comment several times, but I can't seem to understand what you're trying to communicate. Perhaps you could help me out by wording it differently?
Also, was that a typo, or do you really not understand the difference between intravenous and intramuscular?
Correction: Alpha wolfs are so debunked that even the guy who made the initial study debunked it with a study. Not just denounced it.
ah the JAWs effect
Sadly or not, the alpha dynamic will remain a thing in paranormal romance.
Yeah, this one is persistent and annoying. Almost daily I have to explain to people in conversations about dog training. That wolves don't have "alphas" and dogs aren't wolves don't even think like that. Dog training is about gaining trust.
It's like going to a SuperMAX Prison to study human behavior.
Most wolves can't even speak greek, anyway
I’m begging you guys, PLEASE make this a regular series
This needs to be top comment bc this needs to be a series desperately
Indeed!
Yeah for real I was unaware of like half of these
Second that! ❤
Agreed!
Semi-related:
Whenever i hear some guy say, "Im an alpha male," or some variation thereof, my first thought is always confusion about why anyone thinks that announcing themselves as being buggy, unstable, not feature complete, prone to crashing, and not ready for full public use is a good thing.
lmao I mean I like to think that I'm at least a beta, but I'm still prone to crashing randomly so I'm definitely not a full release
Lol yea
I have known many people that could do with a day one patch
The fact that these people come up with terms like "Sigma male" or whichever Greek letter from the list is proof that they acknowledge how flawed their idea is.
Another good one is; "Oh, like the radiation? The weakest, least powerfull and the one with the least penetration capacity?"
As a neonatal nurse, the Vitamin K one pisses me off more than ANYTHING else!!! I've seen too many infants literally DEVASTATED simply because some "instagram-smart" granola mother refused a simple shot. And when I say "devastated", I mean devastated. The kind of devastated that nobody should ever have to see or "live" with. It's just the the most no-brainer decision and yet more and more mothers are choosing not to. It blows my mind and hurts my soul
Indeed. That's super cruel. Feels like society is evolving backwards.
And there are people "raising" their newborn to be raw vegan from birth, without mother's milk. Or to eat light and prana. And they are upset when they go to prison for that...
There is no punishment imaginable that is commensurable or equal to their horrific deeds.
And we know about these few thanks to the news. This is the worst thing. Out of 7 billion there are twice monsters but even if I avoid being about what one of them does in three other side of the world, a relative or coworker sure will bring it to my attention...
I had a similar reaction to the vitamin K one. NICU mom here, my son had the vitamin K shot and I can't imagine how bad his grade 4 bleed would have been without it! Also, thank you for being a nurse, people like you are why my son is alive today!
@@4124V4TA-SNPCA-x You're telling me...that people thought it was smart...to not give their babies THE MILK NEEDED FOR SURVIVAL WHEN THEY'RE LITERALLY AT THEIR MOST FRAGILE. bruh
Based purely on the thumbnail I am going to assume you are here to tell me that there are NOT two wolves inside of me?
Instructions unclear. Ate two wolves. Please advise.
There are two wolves inside of you. That.. that's not good. The physician-recommended number of wolves is zero.

There are 2 types of people 🤣
Periods aren't baby bits, they're baby blanket bits.
Next you'll tell me baby powder isnt made of real babies either
awww
It's not even that, and Hank isn't quite accurate calling the endometrium "cozy" - the unusual thickening of the endometrium in humans actually makes implantation MORE difficult, and is a protection against what is the most invasive placenta type (hemochorial) among mammals (most other mammals' placentas don't burrow directly into mom's blood supply, but have a shallower contact with the uterine wall). It's difficult for humans to expel (miscarry) a failing pregnancy at a later stage, due to the higher risk of fatal bleeding. So the endometrium builds up thickly before conception can even happen, basically to weed out weak or genetically defective embryos before the pregnancy can progress. It's not baby blanket bits, it's wussy embryo keep-out sign bits
(frankly the only mammal with a more dangerous reproductive process than humans is probably the spotted hyena, but i'll let you google that at your own risk)
@Irondragon1945 no it's made of cancer cells....
Not only do wolves not have alpha's but, just like humans, they will absolutely revolt against a parent/pack leader that's too abusive if given the chance.
Alpha and abusive are opposites.
An alpha is capable of leadership and protection.
An abuser is only capable of deception and harm.
The pack leader is the mother and the father of a wolf pack, wolves don't turn on their pack leader, why would they do it? For the right to have intercourse with their own mother or sisters? When wolves get tired of following their parents, they just leave the wolf pack, become lone wolves and try to find another lone wolf frim the opposite gender to form a new wolf pack, we call that maturity...
Wolf packs in the wild are usually just a nuclear family unit, more rarely they get to be a family unit with 3 generations. It's very rare to find wolf packs that don't follow this system in the wild, but when we do find it, the leader of the pack is just the most senior member.
@@777Looper
Ok, it's still not a thing in wolves though. That sounds really cute though❤
@@solsystem1342 It is in packs bigger than a single family. Like the Yellowstone pack.
Or other canines. Dingos, Coyotes, Street dogs.
I love how the furries have to race to the comments to defend the whole alpha thing because it being debunked kind of turns their make believe world on its head. 😂😂😂
I only feel the wifi sickness when I'm on social media.
🤔 i have noticed an increased nausea with certain websites, now that you mention it...
"There is no problem that can't be solved by getting off twitter"

The vitamin K myth is the worst. My mother is a midwife and has dealt with some people like this. New mothers are often anxious and concerned for the babies health and sometimes buy into crazy conspiracies like this. Misinformation spread about medical interventions proven to save lives are disgusting and lead to deaths.
Yep. My own bio-mom bought the vaccine autism bull@#$% hook line and sinker and blames the MMR for me being on the spectrum.
Nevermind all the other unfortunate and unpleasant implications involved here that go against her own reassurances when I was growing up....
Indeed. That's so terrible and inhumane. Infants are already very fragile and this vitamin K shot dramatically reduces the risk of sudden infant death. Which sane person wouldn't want that?
Let's not even start about the vaccine hysterias that are rife in the Western world. One of the best things about science channels is that I can never find the fearmongers here.
@@eunicemwicigi8104 you mean the vaccines that have never been placebo control tested and never been proven to work? Oh you mean the time bill gates gave a bunch of African children polio in an attempt to vaccinate them lmao
@@overlordfemto7523
Please give us some sources for your claims.
Not only can you not draw conclusions about wolf behavior by studying wolves in captivity, you also can't draw conclusions about human behavior by studying humans in captivity, i.e. prison. Nor should you use the behavior of prisoners as a prescriptive model for how all of society should be run. I don't think that's the kind of world you want to live in.
Even if alpha-beta-sigma stuff were an actual part of normal human psychology, it wouldn’t matter because we aren’t cavemen anymore.
We have the ability to ignore our instincts; that’s what makes us more than just apes with thumbs.
we can and have studied apes in the wild and they clearly have alphas and humans are apes
@@jonahblock that depends on the ape species. Chimps operate within a patriarchal dominance-based hierarchy enforced with violence, but bonobos are actually matriarchal and solve their problems with sex instead of fighting. We are equally related to both species.
@jonahblock Wrong. Only specific species of great apes living in environments where they compete over scarce resources exhibit this behavior. Other ape species do not, so you can't make this generalization, nor can you use the alpha ape as a prescriptive model for human society. Evidence from paleontology shows that human ancestors survived by cooperating, not fighting amongst themselves for dominance.
@@jonahblock Given you are now incapable of not speaking like a meathead Joe Rogan, I don't think this coversation has any purpose.
I rescue abused high anxiety dogs. Someone tried the alpha and "beat aggression into them" acts on my GSD as a puppy. Now she's terrified of people as an adult. Not gunshots, thunder, or new experiences either, *just* people. Thankfully 5 years later and she at least approaches people who avoid eye contact and keep a low profile for butt scratches and she's an absolute snuggler with me and my family.
You're confusing "alpha" with abuse. Beating a dog isn't alpha.
That's because it's a dysfunctional mutant that has no place in human territory.
everything about the period blood tweet is so funny. "im not against periods but" like someone was going to accuse them of opposing it like its something women just chose to do?? 😭
I have met men who believed that, as well as those who believed it could be controlled like urination.
So they are mad at *reads again* an actual bodily function. I wish I was still surprised at the level of ignorance. 😑
@@chey7691This is why it's so important to fund education. It's not an individual failing so much as it's a societal one.
@@garethdean6382 No you haven't.
Boys get left out of sex education for girls, so they have no clue what menstruation is or why it happens. Such ignorance should be shameful, but too many parents keep supporting the ignorance.
Do one about the gut microbiome and how we don't understand nearly as much about it as wellness influencers want to pretend we do.
Don't do that.
People might notice that we know even less about the virome, and real fortunes are made on a whole other scale by pretending we do.
Debunkers have to be careful not to go very deep, because, when one does, things always get complicated, because the truth is usually complicated.
I was in a hospital where my sister in law was admitted. One of the nurses was obsessed with gut health and eating yogurt.
My sister in law had tuberculosis and all the 10+ antibiotics she was taking was causing her to lose her appetite... It was wild
To your own point, there is nothing to debunk if you have no evidence to debunk with. Sure, you can debunk the confidence level, but that isn't going to be impactful, and if people stop eating McDonalds because some rando made a video about better gut health that was wrong, then I call that a win.
Someone said the thing about "Wi Fi poisoning" to me and I couldn't help but stare at them for a minute.
And then point out that EVERY electronic device attracts dust like crazy. Allergies are a far more likely cause of all those symptoms, my friend. Maybe dust a lil bit and take a Benadryl?
I think it would be best to not just debunk the wifi thing, but also figure out exactly why people feel that way. I don't think dismissing them will make the problem go away, and it's not like they are trying to be difficult - they have health issues. Maybe it's allergies, maybe it's psychological, maybe something else entirely... the problem is that when people get dismissed (I'm guessing that's what happened before they even heard that wifi myth), some blogger or quack will happily preach to them how electronics are evil.
I've grown up around a bunch of guys that can't even _hear_ about _anything_ related to periods without getting _extremely_ uncomfortable and cutting the convo off. It's refreshing to see a man talk about it without doing that. Thank you!

Maybe it's just jealousy. I'm fascinated by the subject and listen attentively because I'll never get first hand knowledge.
Using '"tweet" is OK. Twitter allows deadnaming on their platform now, so "Twitter" and "tweet" are valid terms to refer to that platform
Amazing comment
Im pretty sure that twitter being okay with it has nothing to do with people still calling it twitter. 😅
Also "deadnaming" is a dumb concept altogether so I too support using the actual name for twitter lol
@@VxV631not to people who are transgender and have had there name changed, it’s used to harass and degrade a group of people by bigots
@@VxV631 why?
I wonder if the "period blood contains baby parts" person had heard about the high rates of "chemical pregnancy", where you basically just have a really early miscarriage, and frequently didn't know you were pregnant. Because the aftermath of a very early miscarriage looks pretty much the same as regular menstruation they may have added one and one and gotten three. (Or, more likely, someone up the misinformation chain had done so.)
Or like, sometimes periods do come out in fleshy clumps because it’s shedding tissue and clotted blood, and people are not super aware of how women’s body’s work. It could just be as simple as someone expecting period blood to just look like normal blood and when they saw clumps of tissue they were like “oh my god it’s a baby”
@@deawinter This is a good explanation. Also, it is one of the most mythologized parts of human biologym anbd we have been making crap up about it forever.
My thoughts as well.
I wondered if the myth came from things like decidual casts. Because when I shed one I fully panicked!
I never heard of this myth until this video.
And 'baby parts' is so vague. I mean babies are made up of amino acids, proteins, DNA, RNA, living cells but they are considering those baby parts then baby parts come out of me when I cut myself or defecate...
And the basic logic of it. Period blood means no fertilisation and no baby. So how could it have baby parts? Human stupidity is mind boggling.
YES, YES, YES! Please do more of these because the rest of the Internet is contributing to lower test scores and outright lies.
Lol.
Ask them about vaccines....
On the sea level rise issue: I have found some folks just didn't know the difference between glaciers and ice bergs and would use the terms interchangeably, and once that confusion was cleared up, they got on board.
But to be accurate, icebergs are glaciers that fell into the sea. Sea ice does not form icebergs normally, though snowfall on a static ice shelf may build up very thick. Also, pressure ridges in large ice fields can sort resemble them.
I have a question about rising ocean levels from melting ice. I've seen reports that when land covered by ice loses a significant amount of weight through melting, the land raises up. It probably wouldn't save Florida (oh well) but is that rise being factored in somewhere?
@juliabliss8145
I haven't heard about that before, so I googled it and here's what I think is a good place to start with research:
oceanservice.noaa.gov/facts/glacial-adjustment.html#:~:text=Though%20the%20ice%20melted%20long,constantly%2C%20if%20slowly%2C%20changing.
In my opinion, articles like this are a great place to start because they introduce you to the terms and definitions used to describe the subject. That way, you can search for other sources and compare info. Always remember to be wary of which sources you trust, and most importantly: have fun (I know I will)! Learning is a gift :)
@@juliabliss8145 Yes! Glacial rebound definitely can have a bigger effect than the global rise in areas that where covered by glaciers during the last glacial period. I believe there are several sites on the Norwegian coast that see sea level drop fast enough to be measured year to year. It can even be seen as terraces in the local geology where the sea level used to be, and even cooler imo, in the fact that there are historic boat docks that are now tens of meters above sea level! I want to say Tom Scott did a video on this some years ago, but it might have been someone else.
Point is, there are lots of places where the terrain is still rebounding from the removal of glaciers sufficiently to cancel out and reverse the effect of global sea level rise, but those effects are, obviously, restricted geographically to where glaciers used to be, and temporally--this occurs over timescales of 10s to maybe 100s of thousands of years, so glaciations older than that won't have measurable effects now and will probably be obscured by the most recent glacial period anyway.
I think many (I won't say most, but many) of the cases of misinformation specifically about sea ice, glaciers, and sea level rise stem from the fact that ALL of those terms have sub-categories and definitions that don't get reported--science communication in general is hard, it's very hard to get right, and is very VERY easy to get wrong. The global MEAN sea level rise that is observed, and usually what is being reported when discussing 'rising sea levels,' averages out the effects over the whole surface area of the ocean to see the overall trend. Local effects like glacial rebound or even just quirks of topography or geology will matter more for those specific areas than the global trend in some contexts, but that's the kind of nuance that's just not possible/profitable/clickable enough for a lot of science communication.
That's a great question. I didn't know the answer so I did some research.
The short answer is, yes, it is being taken into account, and no, it doesn't counteract the effect of melting land ice on sea levels.
It's actually waaaay more complicated than that tho.
One article made the comparison to a mattress when you get off of it, with dents and bulgy parts that relax slowly back into shape, but the description made me think more about a verrrryyy slow waterbed, with ripples. These reactions actually mean some land will end up going DOWN when glaciers melt. As the weight is taken off the dented parts and they slowly rise a little, the bulgy parts sorta ooze very slowly down.
Apparently the earth's crust is still showing reactions to the melting of glaciers from the last ice age 16,000 years ago. Predictions say the Chesapeake Bay area will sink as much as half a foot in the next 100 years.
But to bring in some even more complicated things, scientists measured the surface rising 41mm (1.6 inches) per year in one place in Antarctica and said this was ridiculously fast and wrote a whole paper on why. They said the rise may actually help preserve the West Antarctic Ice Sheet. But if that bit is rising, the bulgy regions around the edges will be sinking too.
Also, it sounds like we may need to think about increased volcanic activity in places that used to have glaciers and earthquakes at the boundaries between those plates.
The articles I liked best were one from NOAA titled "What is glacial isostatic adjustment?" and the Wikipedia article on "Post-glacial rebound". The paper is "Observed rapid bedrock uplift in Amundsen Sea Embayment promotes ice-sheet stability" by Barletta et al 2018.
Here is a persistent myth that I think has even cropped up in a SciShow video: that mantis shrimp can see some brilliant array of colours unknown to humans, because they have 12+ types of colour cones, and humans have a mere 3.
They (likely) can't. In fact, they're not very good at distinguishing colours. This was tested *more than a decade ago.*
Probably what's going on is that humans' colour cones overlap to form a spectrum, and mantis shrimp cones are instead more specialized to alert to their specific frequencies faster.
*(edit)* They can see different types of polarized light, though. Mantis shrimp vision is neat, and I would encourage you to look it up! Colour _variety_ just isn't what's neat about it.
Oh that's super cool as a comment! Please forgive my instantaneous fact checking ritual I go through before I actually tell anyone I know the same factoid, but thanks!
Well what you say is half truth.
First, cone types ranges from 12 to 16 depending on the species in question.
They are indeed bad at distinguishing nuanced colors, if my memory serves right, wavelengths less than 25nm apart are deemed indistinguishable by them.
However, it is a trade off.
They get super high processing speed and better accuracy in exchange.
They not only see polarized light but can distinguish different kinds of polarization, unlike any other animals. Some distinguishing between intensities is also suggested.
So yeah, they don't see like super awesome multi trillion+ color paintings in 32K definition or anything close to that. But they process information much faster and they CAN see brilliant colors unimaginable to us.
Except if you can Imagine your brain processing right and left circular and multi directional linear polarized lights, far red and deep UV light and process it super duper fast with trinocular depth perceiving eyes.
So the way they see the world is still mind boggling and awesome.
And honed to perfection to their needs.
@@4124V4TA-SNPCA-x Mantis shrimp vision is indeed very cool, but seeing polarized light is not unique to them. Distinguishing certain types of polarization (circular?) might be? Not sure.
Either way, I maintain that they do not see any crazy cool *colours* of light.
So far as I know, they see "far red" (~700nm), which is still called red (and not infrared) because it is still within the range of human vision (~750nm).
The ultraviolet light that they see (~300nm) is not super deep in the spectrum, either; quite a few other animals can see it, and humans cones actually can detect about that far into ultraviolet, but it is not normally seen because of the eye lens filtering it out.
@@Koresaurus Nah, AFAIK no other animal can see that many different types of polarized light. Not even close.
And the combination of those? Unique to this clade. Also some species see with 16 different cones... as i told you earlier.
And no creature other than them can distinguish between clockwise and counterclockwise circular polarized light and all types of linear polarizations. Not only at once but by themselves. If you know any other animal can distinguish between clockwise and counterclockwise circular polarized light. But if you think otherwise please release your research papers and books and be rich and famous!
I am aware of the capabilities and limitations of our sight. Also read all research papers about these cool shrimps as they have appeared (but not since respective first publications).
We also have blind spots for example and a limited flicker rate (fps). They are quite the opposite, don't 'hallucinate their surroundings as much as we do and see with super fast (but more crude) processing.
That can be a huge advantage. No tons of optical illusions and mistakes.
I've mentioned trinocular vision before. We cannot even conceptualize it. They have depth perception even with a single eye! Independently movable eyes. Do you have any ide how a double trinocular, thus hexacular vision with awesome depth perception looks like? If you do, please let me know. They absorb an incredible amount of visual information.
And not to get into their awesome biomechanics, especially their forelimb structure as i don't want to write a novel.
I think you don't know enough about them thus you are heavily suspect to the Dunning-Kruger effect.
Everything is on balance of course and tradeoffs must be made. For example human vs. chimpanzee musculature differences (fiber types and distribution), cognitive and memory differences (they have superior short term memory), etc. etc.
But as I told you they are perfectly adapted to their habitat and niche. Like all life after billions of years of evolution. Whether you think they are cool or lame is your opinion. You know what they say about opinions.
I my view all life is beautiful, fantastic, beautiful and unique in its own way. Full of surprises and tons of hidden secrets. All kingdoms.
I never suggested the clade itself is overall superior to any other since that is nonsensical (and I have never claimed to do). But to not acknowledge how truly unique and superior are they is even more so. Much more so. And I am afraid you may do. Hope I1m wrong.
Have a nice week!
@@4124V4TA-SNPCA-x Distinguishing circular polarized light is possibly unique to them, yes... like I said. It does not make sense to sarcastically tell me to present papers to prove myself wrong. And I don't know where you're getting this idea that I think mantis shrimp are lame, when the word I used was "cool".
What a dismissive and pretentious post.
Also, photosynthesis efficiency decreases as temperature rises, because Rubisco is less eager to grab CO2 when it's warm, and not everyone is a C4 chad maize

I enjoyed Mythbusters "back in the day." I'm glad that SciShow is here to bust more myths that have surfaced.
The idea that a period contains baby bits is such an unbelievably ridiculous failure of not just reproductive education, but also logic.
The "who would have guessed?" response describes literally everything I teach my clients. Dog training is remakably simple, but that doesn't mean easy.
As far as bad takes that need straightening in science, I'd say you could do an entire episode solely on the dangers of correlations and how often they're mistaken as causations. This even extends well beyond just science
Yes please, this! So much skepticism of science and medicine starts with a misunderstanding of what's even involved and how we can say that we do or don't know something. Even many researchers and other professionals forget from time to time that correlation does not imply causation.
Not true! This one time I encountered a correlation and it turned out to be a causation! This proves that correlations are causations! /s

I paused the video as soon as I saw the measuring cup with the ice. Clearly this person failed to understand how much ice is locked up ON LAND. *double facepalm*
Not to mention that the glaciers in the ocean have ice above the water level, ice that isn’t displacing water.
@@fizzyoddcod
Actually that's wrong. An object floating in water can't increase the height of water by melting/throwing things overboard. It can technically decrease the water level slightly if it's like a steel boat that sinks (because the water displaced while floating is larger than the amount of water displaced while it's on the bottom of the ocean). Anything less dense than water is already fully displacing its weight in water and therefore even melting won't change the height.
It's still a huge concern for the earth's climate (higher light absorption at higher longitudes might lead to bigger shifts in the climate). Just not for your particular reason.
@@solsystem1342 melting ice cubes in salt water does increase the water level slightly.
@@alolol1000 What kind of flag is that in your picture?
Glaciers in the water are not *necessarily* floating. If they’re not floating, the ice cube in the cup is less than applicable.

It's kinda hilarious. I'm a wolf lover and even I took until a surprisingly recent time frame before I was able to learn the truth about the Alpha myth.
Not helped by circles such as Wolf RP and Furry both still clinging and contributing to its perpetuation, and the fact that dominance/submissive behaviors are still observed in wild packs. The big thing here is that in that case it's just a conflict resolution. The "submissive" wolf is literally just going "Okay, you win" to defuse an argument.
People can barely even tell the diffference between a yawning wolf and a snarling wolf, let alone the difference between (rough!) play, an "argument", and an actual fight.
Honorable mention to the Omega myth. This also came from the same flawed study as the Alpha myth. The actual "rank" that we called Omega is better called a Jester.
Their role is just to play. They're the family's pressure relief. When everyone else is stressed out because, say, a hunt went south, this member may come out of nowhere and start pouncing on wolves, wrestling, and bouncing around and generally being a clown to try to cheer their family back up.
There are documented cases where the "Omega" wolf died, which sent the entire pack into a week-long depression. Howling mournfully, refusing to eat, and just laying around.
As I noted above though, people struggle to identify the difference between rough play, arguments, and fights, though this wolf's attempts to play may be refuted by a grumpy sibling.
Although I probably shouldn't even call it a "rank". It's more of just a particularly playful wolf among the pack. And no, it doesn't have to be a yearling or growing pup, frequently a playful adult will fill this role.
Footnote: Full scale fights basically never happen between members of a healthy pack. Play? Definitely. Arguments? For sure. Actual fights? Almost never.
The most common cause of a fight between wolves is between packs, over territory. Which I shouldn't downplay - the most lethal thing to a wolf in Yellowstone is a wolf in Yellowstone.
It's fun watching the arguments relating to the colloquial "Alpha male" in context to humans down here in the comments.
That whole thing has long ago transcended canids. Oh, and was flawed from the start as an oversimplification of complex factors in human personality.
Of course, some humans really are simple minded enough to let a single label define their entire existence, and then either deliberately or subconsciously, alter their behavior to comply with that label.
Doesn't matter whether that label is "Alpha Male", a political party, or a subculture.
Thank you for the details about the jester/omega role. 😊
WRT the CO2 myth and the need for nitrogen, i think it's important to mention that the nitrogen plants need WILL NOT be coming from the air as I can see many of the conspiracy pushers saying nitrogen isn't a problem because it's ~70% of the atmosphere. Plants need to get their nitrogen from compounds in the soil, so if those compounds aren't being replenished, eg due to deforestation, then plants will also end up dying leaving even more CO2 hence exacerbating the issue.
That is what makes nitrogen fixing plants so cool. It isn't something that all plants can do, and it is a symbiotic relationship with specific bacteria.
Legumes are cool, but they won't fix our problems with nitrogen in the soil.
When we plant new trees in logged areas, we also need to dump a bunch of mushrooms on the tree stumps, and some bacteria in the soil
Also add in the fact that the vast majority of plants cannot perform nitrogen fixation on their own, even though it is essential for plant growth. The vast majority of plant species have symbiotic bacteria or fungi in their roots which do the nitrogen fixation for them.
You need iron in your diet
Well I work in a factory so I breathe it in all of the time. I should be fine.
This is the kind of logic that people who say plants can get nitrogen from the air are using.
I also laugh at people who worry about the radiation from cell phones. They have clearly never lived in places like Hawaii or Florida. You get a way bigger dose of radiation just by taking your hat off when the sun is high in the sky.
It's not TV that will irradiate you, its microwaves...I mean cellphones...I mean wifi...I mean 4G...I mean the next tech thing to com along!
@@garethdean6382 Duh it's obviously AI and ChatGPT that makes you sick!!
Well there were some papers that suggest that there were some problems with some of the early phones because people would be getting a specific type of growth just on the ear that they listened to their cellular phones with, but I don't think it held up long-term and they're supposed to put shielding on phones now to help prevent that just in case anyway. It wasn't the major signals though It was an extra thing that is produced well amplifying the signal on the way out that they were concerned about but I'm pretty sure the follow-up showed that it was just luck in the original study.
The Wi-Fi one is funny because that would actually came from a classroom of school children who put plants on top of their Wi-Fi box and noticed that the plants died. The teacher had to spend a lot of time after the initial report when she realized it was because it was warmer in that spot and the plants had dehydrated😂
you'll get bigger doses in the plane flight getting to hawaii or florida...
different wavelengths of radiation have different effects. Humans are largely made of water, and microwaves warm water faster than other materials. But it has to be a concentrated exposure to have that effect. I bet that is where the misinformation came from...that and the fact that people are naturally afraid of new things they don't understand.
Microwave has been used for communication (like radio) for decades. It hasn't harmed anyone.

The cold myth is probably because if your head gets cold it has the most severe effects. As long as you're swimming fast enough most people can last in almost freezing water for at least a few minutes, but if you put your head under it causes instant disorientation and shock.

Another common myth is that when you throw sodium in water it is the hydrogen that explodes. Yeah, the hydrogen will burn off as it's created, but that's not why sodium explodes in water. You can completely submerge a chunk of sodium where there is no oxygen for the hydrogen to react with, and it will still explode. You can also do this in an inert atmosphere and it will still explode. It's a coulomb explosion, not a hydrogen explosion.
LOL no, you cannot extract electrons fast enough from a substance to cause it to "coulomb explosion"... If you could, desktop fusion would be a reality.
There are two much easier answer. Number one, SODIUM FLOATS! Number two, Hydrogen has a very specific range of flammability, it kind of waits for stoichometry then goes off like a bomb. In short it is its own thermobaric.
@@tsm688 It's possible that the very end of the reaction is a Coulomb explosion, but certainly not of a bulk metal. The research done on it involved only very small droplets of NaK, not the more substantial pieces of pure sodium usually used in demonstrations. When using a macroscopic piece of sodium, it will burn as it floats on/above the water until the end of the reaction when the very last bit explodes with a pop.
I'm pretty sure Sci-Show has already addressed this, but I think it needs to be addressed frequently: The Double-Slit Experient does NOT prove that consciousness collapses the waveform of the particle going through the slits. It's the interaction between the particle and whatever is being emitted by the detectors that causes the waveform to collapse. There's A LOT of woo-wooo shenaneganry going around about this and it kind of drives me crazy.
that is not about the double-slit experiment specifically, but the idea that "any experiment is changed by the observer" meaning "any HUMAN observer" meaning "WE HAVE SPECIAL PSYCHIC POWERS!"
no, it does not mean "human observer", a single damned particle can be an "observer" for this purpose, you're not special.
blergh
@@tsm688 i actually saw a good video that explained WHY the planck measurements exist. basically the idea is that any form of measurement requires bouncing some signal or energy and checking the reflection of that. at planck sizes, any amount of added energy destroys the thing you are trying to measure. or something along those lines.
"Observed" is an unfortunately misleading term in this context. It's not the consciousness observing it that causes it to collapse, but that any observation requires interaction and any interaction causes it to collapse.
@@Candlemancer Exactly 🙂
@@Candlemancer Yeah, whenever I'm trying to explain it to students I generally use 'measurement' rather than 'observation', because it immediately removes the assumption of a human consciousness being involved.
The "more CO2 equals more plants" myth is trivial to show false: if the CO2 was the limiting factor, *the levels would not rise* in the first place. Instead, more plants and algae etc. would grow, and consume all the new CO2 down to the level at which lack of CO2 limits their growth.
We kinda know what limits algae growth, and it's not CO2.

I see people try and claim that an alpha is just a good leader and that people dont know what an alpha really is, and these people really dont realise they are perpetuating confusion and misinformation with miscommunication. An "alpha" is not the same as a elected "leader" or the same as a "parent" figure, an "alpha" is an individual that gains social power through fighting for dominance over that position. Its an incredibly uncommon and rare social hierarchy in nature. Most highly social animals use an elected leader, as in the leader is an individual that can be trusted to protect and feed the group, usually consisting of older individuals with more experience and strength for defence, or they have parental leaders, as in they simly are a group consisting of the parents and their offspring. "Parent" "leader" and "alpha" are not completely interchangeable terms when talking about social structure in animals, lest it cause confusion. So please, stop lying trying to rewrite what "alpha" means, because we already have words for leaders that dont lead with fear and dominance.
On top of that, dominance hierarchies are notoriously unstable and incredibly bad long term.
@@FelisImpurrator its the most annoying when people see one or two incidents of wild animals using dominance hierarchies and claim that that is how those species are when its just a few individual groups. I.e. chimps, there are a few troops that use dominance, mainly common with captive ones, but because of this people assume that's common in the wild too and how humans should act because they are our closest relative, when in reality most wild chimp troops have leader roles not obtained with dominance or fights. Its so bad the Wikipedia page for chimps state that chimps have alphas and link a source that literally says they don't on that statement.

I had to explain the American listed additives as well as the difference in food labeling laws as well as pointing out the difference in products. The main difference between them in an actual side by side comparison is the food labeling laws (the US labels all the fortifications, anti-fungal agents, anti-caking agents, and emulsifiers) and Red Dye 50 which is not allowed in the EU or UK because it’s linked to hyperactivity in children.

The thing with chemtrails, flat earth, and all that crap is that it's trivial to debunk it and extremely difficult to support it, and that's half the reason that those people claim to believe it. Many great videos have been made about the strange communities built up around flat earth, Q anon, and various other bizarre conspiracies and they have much to do with rejecting society and finding their own group identity. Whoever claims to believe the most ridiculous thing demonstrates that they are most committed to the group. It's become increasingly more common in politics too - just watch the circus that has occurred in the US Congress over the last decade.

The heat thing was coming from toddlers afaik. And it makes more sense there, as their heads are proportionally bigger than an adults noggin.
The Alpha Wolf thing came from observation of a pack of wolves in a zoo and it applies there and only there. When the same guy, years later, had the opportunity to observe a pack, or rather family of wolves in the wild he realized his mistake.
The sea level thing is an example of a double strawman fallacy. Global warming causes sealevels to rise by thermal expansion of the ocean and by melting ice over land. But some people misinterpret this fact as "the ice caps will melt and cause sea levels to rise dramatically." Examples of absurd exaggerations of sea level rise are depicted in Waterworld and Cloud Atlas, and some ignorant people take these depictions seriously. So others will point out correctly that the vast majority of ice, the float ice, won't have any effect on sealevels. And then more educated alarmists cry "strawman" while ironically committing the strawman fallacy themselves.

@@PhantasmalBlast Right?! There are real risks that can be mitigated if we'd look at them more seriously. And on the flip side the potential good is huge.

A common misconception i see in people starting to go into the gym to lose weight is that doing all these twists and sit up type exercises will burn belly fat and shred your waist but that's not how it works. In order to lose weight its as simple as doing a caloric deficit and if anything doing core workouts potentially builds muscle there which would lead to size that isnt gonna go away so long as you continue to exercise it
It’s not that simple. If you reduce your calorie intake by too much the body goes into “starvation mode” where it reduces the amount of energy spent on base metabolism. And part of that strategy is reducing muscle mass, since muscles contribute to your metabolic rate; hence “use it or lose it.” The calories burned during moderate exercise is just a small fraction or your base metabolism, _but_ using those muscles signals your body to look elsewhere for additional calories if it needs them … at which point it turns to releasing the energy stored in fat. That’s why it’s important to both exercise and eat a proper diet (i.e. one that doesn’t drastically increase your blood sugar level).
@@trevinbeattie4888 i dont think you understood what im saying. Weight gain and loss isnt the problem. I know that its about balance and consistency.

@SciShow : A myth I would love scishow to debunk is that everybody should eat more protein. I see high protein diets touted as healthy all over the internet, but my understanding from studying food chemistry at university is that on average, people already eat way too much protein and it's unhealthy. My lecturer said that if you eat too much protein, some of it makes it through the small bowel undigested, so the bacteria in your colon break down the left-over amino acids into carcinogenic by-products! Why are health blogs always telling people to eat more and more protein if it gives you cancer? The thing modern people are actually lacking in their diets is complex carbs/fibre, and yet I also see influencers claiming that healthy foods like oats are bad for you just because they're high in "carbs". Carbs are not all equal, bruh

Was expecting to see "boiling water freezes faster" myth to be debunked here but well....
That is just a simple application of thermodynamics! If you put hot water in your freezer you are adding much much more heat than cold water. The extra heat warms up the whole freezer!
The actual truth is hot water cools faster at room temperature than lukewarm water again because of thermodynamics and entropy.
@@nikkiewhite476this is actually the entire mechanism that makes freezers and refrigerators possible too! Evaporated liquids have been shown to significantly cool things down. This is also the exact same mechanism that sweating uses as well, which makes us humans nature’s best athletes as we have a cooling system that allows us to run for exceptional distances without burning out which for ancient Paleolithic and Neolithic hunter gatherers allowed them to chase their game for miles until their prey passed out from exhaustion.
@@nikkiewhite476 I understand how the boiling water readily changes to vapour and takes with it a lot of energy, reducing the average overall temperature. But as this occurs, eventually the (remaining) water reaches the same lukewarm temperature. At that point, is there something different about the water that started hot and became lukewarm versus the water that was lukewarm to start with? Because if not, the hot took time to become lukewarm, and only once it was did both take the same path and time to cool the rest of the way, so the boiling water must take longer in total.

The head heat myth was definitely exacerbated by the movie Loser.
The main character always wears a hat, and when asked why, he says something along the lines of, “you lose most of your body heat via your head.”
yeah but this was counteracted by Kick Buttowski, a cartoon character who kept one single icecream from melting in the summer heat inside his crash helmet.
when asked how this was possible, he replied:
"it always pays to keep a cool head."
so yeah. it balances out I think
Doubt it. Never heard of that movie but I have military relatives and basically everyone I'm related to believes the head heat myth.
You also can't get meningitis from your head being cold, it's not how meningitis works. Not sure if this myth exists anywhere other than in post-soviet countries.
Please look into and address "gluten sensitivity." While we lived in Germany, we never experienced or heard of it. When we returned to the States, oh my goodness, it seemed like everyone was gluten sensitive. Is the EU-banned and US-allowed potassium bromate the culprit? Please advise.
There are people that are definitely sensitive to it. Celiac disease is an immune response of the body against gluten proteins which is a result of a gene abnormality. There's also gluten intolerance, which is clearly documented and can be tested for, but the reasons for it aren't understood. It may not be the gluten itself; it could be an intolerance of some associated carbohydrates or of wheat specifically.
There is also a much larger portion of people who believe that gluten is simply bad for you. They also tend to associate any kind of digestion issue with gluten, whether or not its even present, while overlooking instances where they feel fine even though they've eaten gluten. It's a combination of the nocebo effect (if you think you will feel bad, you will) and the frequency illusion (once you become aware of something, you start noticing it more often).
Gluten-free has become a recent fad diet.
Yes!! Love this concept. More people need to see these videos. Please do more on the food myths, they've been out of control for a long time lol
